6. What does the Male Reproductive System Do? The male sex organs work together to produce and release semen into the reproductive system of the female during sexual intercourse.

7. The Stages of Puberty • The first stage: • the scrotum and testes grow larger. • Next: • the penis becomes longer, and the seminal vesicles and prostate gland grow. • Finally: • Hair begins to appear in the pubic area and later it grows on the face and underarms.

8. The Sperm Sperm develop in the testicles within a system of tiny tubes called the seminiferous tubules.

9. The head contains genetic material (genes). The sperm use their tails to push themselves into the epididymis.

10. The Fertilization When the male ejaculates during intercourse, semen is deposited into the female's vagina.

11. The main anatomically male sex organs are the penis and the testes TheMaleReproductiveSystem

27. Varicocele. This is a varicose vein in the network of veins that run from the testicles. 

28. Testicular Cancer. This is one of the most common cancers in men younger than 40.

29. Testicular Trauma. Even a mild injury to the testicles can cause severe pain, bruising, or swelling. Most testicular injuries occur when the testicles are struck, hit, kicked, or crushed. Continue
